Matweld Tempindic Temperature Crayon 38°C (100°F)

Matweld Tempindic temperature crayons are calibrated markers that melt at a precise temperature to indicate when metal surfaces reach the required heat during welding operations. With ±11% accuracy and compliance with European RoHS regulations, these lead and sulphur-free crayons are ideal for pre-welding, inter-pass, and post-weld temperature monitoring. Simply mark the metal surface and the crayon melts when the rated temperature is reached, making it an essential tool for welders and fabricators requiring precise thermal control.
